2002 Injector

2002 160k miles. Engine check light shows one bad injector. Happened suddenly. misses and check light blinks at idle.

I baby the truck and use Techron cleaner in a fillup every 5000 mi. when oil is changed. No other issues. Changed plugs 10k ago.

Many questions.

1. what kind of mileage should I get on injectors. Is 160k high or low on failure

2. Should I attempt cleaning that injector?

3 Should I change all of the injectors?

4. New OEM or Remanufactured

5. Vendor recommendation

6. Any other recommendations?

 

There are some companies out there that can rebuild and blue print your existing innectors but that can sometimes cost the same as buying a new set, and the down time of service turnaround. Benefit is having a matched set of "new" OEM injectors.

When I had an injector go out I purchased the Dirty Deeds 270cc pieces. After about 6 months of use I'm satisfied with performance and initial cost.

You can always try cleaning the injector. There are plenty of youtube tutorials and online guides for accomplishing this. However if your injector solenoid is toast cleaning isn't an option.

Items like this are a good idea to change as a set. No point in doing the work if you may have to replace another injector in a few weeks. It's also a good idea for combustion efficiency, mileage, and emissions to have a matching set. Look at it as the same as spark plugs or ignition coils. You may be able to get away with just changing one or two, but best practice is to replace the set.

 

I had my 8 injectors cleaned Professionally at RC fuel injectors in Torrance,Ca. I have a 2006 tundra at 160k miles when this was done.

Service was $25 per injector ($200 total) came with a 24 hr turn around, performance report, warranty, new filters, seals, and o-rings. O-rings and seals for all 8 at the dealer was $70 alone, Amazon cleaning kit is about $30 + Carb cleaner and rags.

Three of mine were dripping before being serviced. Only reason I serviced them is because I was doing work on the fuel rail.

I thought about cleaning them
myself but I just didn’t trust it. It’s also a lot of work to get to them and didn’t want to do it twice.

I recommend taking them out yourself and taking them to a place to be cleaned or serviced. No need for new injectors, unless you want want to spend the money. If any of them are bad they usually sell rebuilt ones.

Same 2002 Tundra and I replaced my injectors with 12 Holes from Dirty Deeds.

It was 2018 (160k miles) and time to reinvest back into the truck. I wanted to ‘clean’ the existing injectors, BUT that required removal and 2 day turn around time with $250 cost. No go Bobo.

Decided to spend ($330) at the time for new rebuilt Denso 12 Holes shipped to the door. It was about a 5 hour job. Truck drives better in terms of shifting. The gears hold a little longer on the down pedal at lower speed and the lazy down shift coming from high speed down to a slow turn and acceleration are gone. The gear is there when you go to accelerate. You can also feel the downshifts slightly now.

I highly recommend them after 2 years. Engine seems to purr a little better. Brand New Injectors cost about $800ish iirc. The 12 Ports DO NOT give me better OR worse MPG. Do not do them for MPG.

They DO provide better torque feeling and shifting qualities/throttle response. They make the truck funner to drive IMO. I’ve read elsewhere the Denso 12 Holes Injector has a more robust internal design, but cannot prove this.
